The criteria of expediency of selection of grape varieties for freezing by natural and alternative methods are determined. The physico-chemical and phenolic composition of natural and alternatively frozen grapes of varieties grown in the conditions of the Northern Black Sea region were investigated. The physical and chemical properties of wine materials for ice and for wine type "Icewine" are investigated. The technological application of must bland from natural and alternative frozen grapes is substantiated, The expediency of one-time use of yeast together with complex supplementation and inactive yeast has been determined to achieve conditions in the wine material: 150…190 g/dm3 of mass concentration of sugars, 1,0 ... 1,5 g/dm3 - volatile acids, 9...10% v/v ethanol. On the basis of experimental research, two technological schemes were developed: technology of icewine by freezing grapes natural way and technology of wine "Icewine" type - by an alternative way. Production of varietal and blended wines of icewine and wine "Icewine" type is proved to economically feasible.
